SPECIFICATION forming part of Letters Patent No. 735,847, dated August 11, 1903.

Application filed PebrnarylE, 1902. Serial No. 94,295- (No model.)

To all whom it may concern;

Be it known that LWARD O. WALKER, a citizen of the United States, residing at the city of Battlecreek, in the county of Calhoun and State of Michigan, have inventedcertain new and useful Improvements in Binders, of which the following is a specification.

This invention relates to improvements in self-binders. p

The invention relates particularly to the grain adjusting and carrying means.

As heretofore constructed a serious defect in self-binding harvesters has been the clogging of the grain or the leakage of the grain at the upper ends of the elevating aprons or canvases which carry the grain from thelower platform to the binding-deck above. The space between the aprons and deck is the point of deficiency. Another serious matter in this connection has been that there was no efficient adjusting means and no eflicient butterboard to keep the grain perfectly straight and true to deliver it properly to the bindingmechanism. Heretoforeadjustment of butter-boards and of the decking generally has been accomplished by the manipulation of two or more levers, and when adjusted the different parts are thrown out of true and there is'practically but one position in which such old devices will be successfully operative. That the butter-board may operate effectively the grain must be advanced evenly, and the butter-board should be adjusted Without losing its proper angle to the decking over which the grainpasses.

It is the. object of my invent-ion, therefore,

to provide an efficient means of carrying the and the straw parallel.

Further objects relate to the details of con- Figure 1 is a detail end sectional elevation of parts of a harvesting-machine looking for ward, indicatingthe relative position and lo cation of the various parts of my improved device in the harvester.

and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is adriving-wheel, represented in conventional form.

13 B are elevating aprons or canvases carried on suitable rollers in a casing K for the elevation of the grain to the binding-deck.

L is the upper roller of the under apron. A strip of stationary decking F, having trans verse slots through the same, is placed quite close to the roller L. This strip of decking F overlaps the movable binder-decking C, so that the gra n passing over the decking F is delivered upon the same to the packer-fiugers C.

O is the needle of the binding mechanism, shown in conventional form, and D is a cover or shield above the binder-deck.

Beneath the decking, F is a shaft E, carried in suitable boxes 0. a at each end, and on the rear of the same is a sprocket-Wheel E" or other suitable driving means connected with the other moving parts of the machine. The sprocket-wheel E is preferred, because it will thenlbe only necessary to extend the sprocket chain, as M, over the sprocket-wheel to properly drive it, as appears in Fig. 2. Transverse fingers E are provided on the shaft E, which extend outwardly and are then bent off at an angle and slightly curved, so that in operation the outer portions of the arms will strike up through transverse slots in stationary decking F and carry the grain forward and will then be withdrawn from contact with the grain substantially at right angles. This particular form of fingers is adapted to prevent any clogging of the grain at this point by drawing the same through the slots in the decking.

The decking 0, along with the packing and knotter mechanism, is made adjustable back and forth in any of the well-known ways now made use of in binders of this class for the purpose of shifting the knotter mechanism along the bundle as may be desirable for the varying lengths of grain.

The butter-board mechanism is operated and adjusted as will be hereinafter described. It is adjustable back and forth by means of a leverf, which is acted upon by a pin j on the under side of the adjustable deck 0, which is made to strike this lever f and carry the butter-board toward the rear when the knott-er mechanism is carried toward the front. This distinctly appears in Figs. 1 and 5. The lever and its connections to adjust the butter-board mechanism will be hereinafter completely described.

On the shaft E, which is fixed from longitudinal movement, is the butter-board mechanism, the same being adapted to reciprocate longitudinally on the shaft. This longitudinal movement is accomplished by boxes or bearings G G on the bracket G, which carries the butter-board H. These brackets contain bushings, (illustrated at 70.) A loose collarf embraces the shaft E just back of the bracket (1 and is controlled by the forked 1everf, which is pivoted at and is acted upon by the pin j, heretofore referred to, when the binder mechanism and butter-board are shifted for the proper adjustment for short grain. A spring g holds this collar against the bracket (1 and also holds the bracket G under tension, and by this means when the shaft E is rotated the butter-board H will be reciprocated back and forth, striking against the butt-ends of the grain to even up the same as it is delivered to the packers C by the carrying-fingers E, as will clearly appear. from the detailed description of parts to follow. The leverf is supported by a pin 70 on the beam I. The lever is slotted at It to permit the required movement as the butter-board is shifted and is acted upon by the springlo, which surrounds the pivot 70 and is connected to the lever f and to the beam 1, which throws the free end of the lever normally toward the rear of the machine and holds the bu tter-board normally toward the front of the machine. When the lever f is moved by the pinj contacting therewith, it will carry and hold the butter-board normally toward the rear of the machine without in any Way varying its reciprocatory motion. It will be seen from this that when the binder is adjusted back and forth by means of the lever N with rock-shaft connection N the butter-board is automatically adjusted in relation thereto to secure the best results. The pinj is so located on the deck 0 that it may be moved forward a short distance before engaging the lever f" to shift the butter-board, so that the butter-board is shifted for very short grain only.

The butter-board is made up of a central part rigidly connected to the bracket G. To the edge of this I hang a guide or wing 11, the free end of which is supported by a link 0, which is pivotally connected to the guide at c and to the bracket or frame I at 0, so that the grain will be forced down the decking and guided into position to be acted upon by the butter-board. A section II is hinged at b and is held normally in line with the central part by means of the spring 171.. This hinged portion is provided as a guide for the grain as it is carried forward after being properly adjusted and is made yielding, so that it will not prevent the adjustment of the decking C while there is a bundle on the same. i

The boxes G are provided with bushings (illustrated at Fig.12) containinglongitndinal slots 72 at intervals around the same in which are placed bearing-balls h, which enable the structure to reciprocate readily back and forth on the shaft E, upon which it is supported.

Supported upon an arm J, projecting from the casting J, is a guide-roller J, adapted to reciprocate in suitable guides t' on the under IFS side of the stationary decking F and keep the butter-board in properrelation to the decking. The casting J embraces the shaft E like a collar and has a cam on the side toward the front of the machine, as clearly appears in Figs. 3, 4, and 10. This casting J is secured to or is a part of the bracket G, which carries the butter-board. A shield 1' projects from the bottom of the butter-board over the stationary decking F, which is cut away at this point to permit the reciprocation of the butter-board mechanism.

The front end of the shaft E is hollow and contains a longitudinal slot e. (See Figs. 3 and 8.) Within this hollow shaft is a plug or plunger Z, having bearing-balls Z Z toward each end, as clearly appears in Fig. 8, the same being positioned to counteract the strain and permit the plunger Z to reciprocate freely. Through the plunger Z is a key 6, which engages the bracket (1; which has a collar embracing the shaft E, so that the bracket will be rotated with the shaft. This bracket carries an antifriction-roller d, which is adapted to engage the cam-face on the bracket G, and the bracket is held to the same by the spring g, so that the bracket G, which carries the butter-board, will reciprocate back and forth by the rotation of the shaft E.

In operating my improved binder the grain is carried up the elevator-canvases in the usual way, when it is engaged by the fingers E on the shaft E and carried forward across the stationary decking F, where it is engaged by the packers 0. As these fingers E are shaped to withdraw at right angles through the decking F, there is no possibility of their entangling straw and clogging at this point. The fingers E engage the straw practically as soon as it leaves the apron, so that it cannot be drawn down by the apron. The butter-board is on this same shaft and evens the butts as they are carried along in this way and forced down to the packers of the binder mechanism. In an ordinary length of grain no adjustment is necessary. When the grain is very short, by operating the lever N the binder mechanism is carried toward the butts-that is, toward the butts of the bundleand the butter-board is carried in the opposite direction and delivers the grain properly to the binder even though it is extremely short.

I have shown the details of my device fully because I consider that they are in the form best adapted to the purpose intended; but I am aware that many of the devices I have in lessening friction and securing superior operation might be dispensed with and still have the device fairly successful in operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
